Is Kanawha County, WV in a flood zone?
FEMA's National Risk Index puts Kanawha County's flood hazard at the 97.9th percentile nationally — well above the national norm for flood hazard — driven by inland rivers and flash flooding rather than the coast — FEMA's model puts a flood event here at about 4.2 times a year. That's a county-wide figure, not a per-address one — FEMA's parcel maps are a live lookup, not a bulk file.
Mandatory flood insurance compliance in Kanawha County
Homes with a federally backed mortgage inside Kanawha County's mapped high-risk flood zone (the Special Flood Hazard Area, or SFHA) are legally required to carry an NFIP flood policy.

Across all residential structures in Kanawha County, not just the ones FEMA mandates, 1.5% carry an NFIP policy — most flood damage nationally happens outside the mapped high-risk zone, so that broader number matters too.
